Electrochemical module with stack, clamp, flowing pipe, and pressing mechanism
A recently granted patent (Publication Number: US11996592B2) discloses an electrochemical module designed with a unique configuration to enhance efficiency and functionality. The module comprises a stack of electrochemical elements with an electrolyte layer, electrode layer, and counter electrode layer arranged on a substrate via an annular sealing portion. A clamp with a flowing pipe and pressing mechanism is used to supply or discharge gas to the annular sealing portion. The pressing mechanism includes a first screw member and a second screw member that presses the flowing pipe, ensuring a secure and efficient gas flow within the module.
Furthermore, the electrochemical module includes features such as a thermal expansion rate matching between the pressing mechanism and flowing pipe, an elastic plate-like member for stability, and a fastening member to secure the stack. The substrate of each electrochemical element is designed with penetrated portions for gas flow, forming a supply passage through the annular sealing portion. The module can be integrated into electrochemical devices for fuel conversion or power extraction, contributing to energy systems with waste heat utilization capabilities. Overall, the patented technology offers a sophisticated solution for electrochemical applications, ensuring reliable performance and enhanced operational efficiency in various energy systems.
